in the traditional systems of irrigation and exploitation of water sources, especially the water sources behind dams, there isn't regular and consistent plan for their management and this can be caused the weakness of irrigation performance. in this connection, using both of optimization methods and geospatioal information system (gis) together can improve the performance of irrigation pro...

In this paper I examine some of the factors influencing technology development and attempt to explain whether CLIA '88 enhances the opportunities or exacerbates the problems for U.S.-based technology development. The viewpoint I express is concentrated on the clinical chemistry segment of the diagnostics arena.

Refactoring is a widespread method to improve the structure of an application’s source code without affecting the application’s behavior. However, since refactorings are defined for single programming languages or programming paradigms, refactorings do not consider the interaction of source code of different programming languages. Thus, refactoring can break applications written in different pr...

Functional and logic programming are the most important declarative programming paradigms, and interest in combining them has grown over the last decade. Early research concentrated on the de nition and improvement of execution principles for such integrated languages, while more recently e cient implementations of these execution principles have been developed so that these languages became re...

In this paper we describe the distribution problems faced by one of the largest retailers in the distribution and sale of fast moving consumer goods in the U.K. The paper describes an initial solution method, which is then improved by a novel form of simulated annealing. A computational experiment for the improvement algorithm has been also carried out in order to illustrate the flexibility of ...

a new retrofit targeting procedure, based on pinch technology has been developed. the new procedure considers existing structure of a given network and finds the most compatible configuration with the network. to achieve this aim, the procedure uses a linear programming technique that maximize the compatibility. good compatibility between old and new networks helps to make the best use of capit...
